Strength

Question 1

What is strength?

Answer 1

1. Ability to contract the muscles with maximum force, given constraints
2. Ability to exert musculoskeletal force against an external object

Question 2

Strength is the ability to contract the muscles with maximum force given the constraints of what 4 things?

Answer 2

1. Structural/anatomical factors
2. Physiological/bio mechanical factors
3. Psychoneural/psychosocial factors
4. External/environmental factors

Question 3

In fitness terms, strength is the ability to exert musculoskeletal force against and external object and it comes from what 4 main sources?

Answer 3

1. How the body is put together as an efficient machine
2. How the internal systems work to create energy and promote repair, remodeling, and growth in response to training
3. How skills, attitudes, belief systems, and tolerance to pain interrelate to allow the body to function at peak efficiency
4. How factors external to the body can be manipulated to produce greater force output

Question 4

What is 1RM?

Answer 4

“Max” or “one rep max”; maximum effort for one repetition of a weight training exercise

Question 5

What is limit strength?

Answer 5

Absolute strength enhanced by hypnosis, electrotherapy, ergogenic substances(nutritional supplements or drugs), or other techniques. Such aids increase the potential for strength above normal capacity

Question 6

What are the 3 kinds of limit strength?

Answer 6

1. Eccentric strength
2. Static strength
3. Concentric strength

Question 7

What is static strength?

Answer 7

Strength required to resist and control the weight resistance involved in a stationary position

Question 8

What is concentric strength?

Answer 8

When the force generated by the muscle(through concentric contraction) exceeds the load opposing its contraction

Question 9

What is absolute strength?

Answer 9

The amount of musculoskeletal force you can generate for one all-out effort. Developed through heavy weight training, typically involving above the 80-85% of maximum effort for each lift

Question 10

What is speed strength?

Answer 10

The ability of the neuromuscular system to produce the greatest possible impulse in the shortest possible time. Defined by Work/Time, where Work is defined as Force x Distance.

Question 11

What is starting strength?

Answer 11

The ability to recruit as many motor units (MU’s) as possible instantaneously at the start of a movement

Question 12

What is explosive strength?

Answer 12

Ability to exert strength or force as rapidly as possible in a given direction.

Question 13

What is anaerobic strength?

Answer 13

Musculoskeletal force and energy production that does not require oxygen.

Question 14

What is linear strength endurance?

Answer 14

Sustained all-out maximum effort over an extended period of time

Question 15

What is nonlinear strength endurance?

Answer 15

Ability to perform an activity with exceeding explosiveness over and over for an extended period of time

Question 16

What is aerobic strength?

Answer 16

Musculoskeletal force and energy production that requires oxygen

Question 17

What is general strength?

Answer 17

The quality of being physically strong

Question 18

What is specific strength?

Answer 18

Limit strength obtained specific to the particular muscle groups that will be most involved in the performance of the events/activities in which are to be performed

Question 19

What is special strength?

Answer 19

Specialized type of strength gained that is specific to a particular sport or activity skill/event.

Question 20

What is the strength curve?

Answer 20

Graphical representation of how the human body generates and applies force in a specific direction

Question 21

Define force.

Answer 21

The interaction that creates work, action, or physical change. Such as a push, pull or lift

Question 22

What is Fmax?

Answer 22

Aspect of the strength curve that stands for force max. Fmax divided by Tmax is the definition of explosive strength.

Question 23

What is Tmax?

Answer 23

Aspect of the strength curve that stands for time max. Measurement of how long it takes from the beginning of upwards(concentric) movement to exert maximum force.

Question 24

What is the equation for power?

Answer 24

P = fd/t

Power is equal to force times the distance per unit of time

Question 25

What is the equation for explosive strength?

Answer 25

Explosive strength = Fmax/Tmax

Question 26

What is functional strength?

Answer 26

Category of strength that can improve the ability to perform everyday tasks or sports skills, builds overall strength and balance, and augments resistance to injury

Question 27

What is the amortization phase?

Answer 27

“Transistion Phase”; represents the brief time between concentric and eccentric movement

Question 28

What is ballistic stress?

Answer 28

Commonly used by individuals to help them to develop and improve explosiveness and power in the body. Achieved by accelerating and releasing weight into space

Question 29

What is ballistic movement?

Answer 29

Muscle contractions that exhibit maximum velocities and accelerations over a very short period of time

Question 30

What are plyometrics?

Answer 30

Exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing both speed and power

Question 31

What is compensatory acceleration training(CAT)?

Answer 31

Weight lifting technique used to develop explosive strength whereby you accelerate the bar as leverage improves through the movement
